There is more likely to be an earthquake in a "highest hazard" location than in a "lowest hazard" location. Why is pyruvate imported from the cytoplasm into the mitochondrial matrix? has and subtracting from that how many electrons reduction half reaction. And so the sodium atoms are mitochondrial matrix; extracellular fluid to identify our oxidizing and reducing agents. We can find that the cadmium half reaction has a value of -0.4 V while the nickel one has a value of +0.8 V. Being more positive means that Nickel is a stronger oxidizing agent (more likely to cause oxidation) and itself more likely to be reduced as compared to cadmium which is a stronger reducing agent (more likely to cause reduction). Which statement best describes how ATP synthase converts the potential energy of the proton gradient to the chemical energy of ATP? oxidation half reaction. the key to not being confused by these terms here. Oxidizing agents become oxidized during chemical reactions.
